UICheck vs Percy

Percy (part of BrowserStack) is visual regression testing: your test suite takes snapshots, Percy compares them with approved baselines and you review what changed. It answers “did anything change?”. UICheck answers “is anything wrong?” first: it tests a live URL on every screen size and finds layout bugs even on the first run. Once a project looks right, UICheck can also keep its approved screenshots and show what changed on every later run, without test code.

Choose Percy if

You have an automated test suite and want every component change reviewed
You need snapshots of app states that only a test script can reach

Choose UICheck if

You have no test suite, or test sites built on WordPress, Shopify or Webflow
You want bugs found on the first check, not just changes
You want to compare the build with the design

Or use both

Many teams need only UICheck: layout bugs, Figma and visual baselines on real pages. Teams with a large test suite can keep Percy for component snapshots and use UICheck for the full pages on every screen size.
